“…It is noteworthy that numerous recent studies have reported hexactinosidan-dominated Mesozoic sponge faunas associated with sea-level highstands and accompanied by low sedimentation rates (e.g., Vodrážka et al 2009;Schneider et al 2011). The hexactinosidan sponges described in this paper proliferated under similar sedimentological conditions: mud mounds developed during transgression and subsequent stillstand with reduced but still existing background clay sedimentation (Fernández et al 2006).…”

“…a very low sedimentation rate and/or upwelling of cold oceanic waters from the Tethys Ocean (compare e.g., Mehl and Huschke 1995;Mehl and Niebuhr 1995). Only a few species of hexactinosid and lychniscosid sponges have been noted in the Upper Cretaceous shallow-water deposits (see Schrammen 1912;Reid 1968;Ulbrich 1974;Mehl and Niebuhr 1995;Vodrážka et al 2009). Out of the numerous Cretaceous dictyids, similarly to recent hexactinellids, only some species could tolerate shallower-water conditions.…”

“…Redeposited sponges are usually crushed ) and/or phosphatized (e.g. Vodrážka et al 2009;Świerczewska-Gładysz and Olszewska-Nejbert 2006;Świerczewska-Gładysz 2009, 2011), but sometimes nearly complete sponges with a siliceous skeleton and an undestroyed surface are found even in glacial deposits (undescribed specimens collected by P. Czubla from Mąkolice near Piotrków Trybunalski, Central Poland).…”

Świerczewska-Gładysz, E. 2012. Hexactinellid sponge assemblages across the Campanian-Maastrichtian boundary in the Middle Vistula River section, central Poland. Acta Geologica Polonica, 62 (4), 561-580. Warszawa.The sponge fauna from the Upper Campanian-lowermost Maastrichtian succession of the Middle Vistula River valley (central Poland) is represented mainly by dictyid hexactinellid sponges (Hexactinosida and Lychniscosida). Their greatest abundance and taxonomic variability is noted in the "Inoceramus" inkermanensis Zone (Upper Campanian), and they are less diverse in the overlying (Upper Campanian) Trochoceramus costaecus Zone and lower "Inoceramus" redbirdensis Zone. In the upper "Inoceramus" redbirdensis Zone (basal Maastrichtian in the sense of the Tercis rather than the Boreal definition) they are extremely rare. With the beginning of the Maastrichtian the number of dictyid sponges gradually increases.The observed changes in the abundance and taxonomic variability of the dictyid sponges indicate environmental changes in the latest Campanian-earliest Maastrichtian sea in the area. It seems that changes in basin bathymetry, confined to eustatic sea-level changes in the latest Campanian and early Maastrichtian, were the most important factor. Progressive shallowing of the basin in the latest Campanian drastically restricted the development of dictyids. In the peak regression, the sea level could have fallen to only several tens of metres. The gradual recovery of the sponge assemblages correlates with subsequent deepening of the basin with the start of the Maastrichtian.

Laocoetis piserai n. sp. (Hexactinellida, Porifera) from the mid-Cretaceous (i.e., Albian–Cenomanian) of James Ross Island is the first record of a fossil sponge from Antarctica. This new occurrence of a formerly widespread genus was restricted to relatively deep waters on the margins of an active volcanic arc. Its occurrence in Antarctica is further evidence that the genus Laocoetis underwent a dramatic reduction in its geographic range through the Cenozoic. The only living species of the genus at the present day is Laocoetis perion from Madagascar.
